Former Cal football star Marshawn Lynch, widely projected to be a first-round pick in the NFL draft, is the subject of a restraining order accusing him of choking, slapping and sexually assaulting a woman, according to a media report.

The woman making the accusations was Lynch's high school girlfriend, said his attorney, M. Gerald Schwartzbach, adding that Lynch had broken off their relationship and denied any wrongdoing.

"When the person who is being accused is of a celebrity status and, one would expect, is about to become quite wealthy, unfortunately, it is not surprising that there are, at times, people who resent that person, who are jealous of the person, who want a piece of the notoriety and the money," Schwartzbach said Sunday.

Lynch, 20, allegedly assaulted the woman on Dec. 13 in Oakland, prompting her to file a civil complaint six days later, KCBS radio reported this weekend. A judge issued a restraining order on Friday, the station reported, citing court documents.

Lynch did not return phone calls from The Chronicle Saturday or Sunday. A statement issued on behalf of the university read, "We knew about the situation and are cooperating with the authorities."

Schwartzbach said he hadn't seen the restraining order but didn't believe there was any merit to the allegations.

"I'm convinced that Marshawn did not do any of the things that he's being accused of," Schwartzbach said. "Based on everything I know, he's not just a great athlete, he's a great kid. I don't think that these allegations are simply consistent with his life history."

Lynch was at the woman's home with a third person, who confirmed that nothing untoward occurred, the attorney said. The third person's account "impeaches" that of Lynch's former girlfriend, Schwartzbach said.

No criminal charges have been filed by Alameda County prosecutors, who are reviewing material submitted by Oakland police, he said.

Lynch, who left school without graduating, earned the Pac-10 Offensive Player of the Year award and All-America honors last fall while at UC Berkeley and is widely projected to be a first-round pick in April's NFL Draft. He ran for 1,356 yards and 11 touchdowns in the season just ended to move into second place on Cal's all-time rushing list. The running back ended his career there with 35 touchdowns in 35 games.

On top of any of his highlight-reel runs, Lynch will probably be best remembered by Bears fans for his impromptu zigzagging ride across the Memorial Stadium field in a utility vehicle after Cal's overtime win against Washington on Oct. 21.
